Stainless steel electric resistance welded (ERW) pipe is manufactured by rolling metal and then welding it longitudinally across its length. SS ERW pipes are manufactured from Strip/Coils and can be manufactured upto 12” NB. For sizes from 6” NB to 36” NB, Metline can produce fabricated pipes, made from cut to size plates. The plates are first rolled and then 100% X-Ray welding is done. Since large diameter stainless steel 317L welded pipes cannot be made on a rolling mill, we produce such pipes by rolling cut to size plates and performing welding operations on them. All large diameter 317L welded stainless steel pipes, are produced as per ASTM A358 Class I to Class V specifications. Meanwhile, stainless steel 317L welded pipes in sizes from ½” to 12” (SCH 5, SCH 10, SCH 40) can be produced on rolling mill as per ASTM A312 specification.

Due to their high corrosion resistance and top quality, our stainless steel 317L welded pipes are widely supplied to many industries, such as electricity, petroleum, natural gas, chemicals, shipbuilding, heating, papermaking, metallurgy and so on.

Metline Industries is a global manufacturer and supplier of stainless steel 317L welded pipes, stainless steel ERW pipes and large diameter stainless steel 317L welded pipes, with ex stock inventory of 600 tons. We manufacture, stock and sale ss 317L welded pipes in round, square and rectangular form with either mill finish or polished surface. Mill finish (Annealed & Pickled) stainless steel 317L welded pipes are generally used for industrial applications, where as polished ss 317L welded pipes are used for architectural and structural applications. Given our daily sales volume of 20-30 tons of stainless steel 317L welded pipes in India, we are capable of offering our customers with the best quality at lowest prices in the industry. We sincerely welcome new and old customers to co operate with us for all their stainless steel 317L welded pipes requirements.

About 317L Stainless Steel

317L is the low-carbon derivative of SS 317. The metal maintains its high strength and strong corrosion resistance; however, the carbon content does have several effects. 317L has greater strength under welding; its products are stronger.

Like 317, stainless steel 317L does not respond or harden from heat treatments. When hot working, the metal should be heated ideally within the range of 2100-2300°F. Dropping below 1700°F will cause the metal to be unresponsive. For these reasons, 317L is effective in high temperature areas that experience high rates of chemical corrosion, creep, and stress-to-rupture.

317L is commonly utilized in chemical environments. It has shown itself to be effective in conditions where acids are present, such as acidic chloride. The metal is resistant to corrosion from such substances. As such, it is common to find 317L in equipment used in pulp and paper mills. The acidic environment requires a strength, corrosion resistant metal.
